BEADING-TOOL.

Application filed. September 27, 1915.

To all whom it may concern: I

Be it known that I, THOMAS LUND, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Beading-Tools, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to rotary burnishing tools and in particular to rotary tools used in burnishing heels of shoes. customary in the manufacture of shoes such, for example, as childrens shoes known to the tradeas cacks to perform three burnishing operations upon the heels. The entire outside periphery of the heel is burnished, a bead is made around the outside peripheral edge and a bead is made across the breast. It is necessary to have a comparatively small beading wheel for the last operation owing to the sharp indentation at one end of the breast in this type of shoe. Heretofore it has been the practice to use three separate tools for these three opera tions. It is the object of my invention to provide a tool which shall be simple and convenient in operation, cheap to manufacture and by means of which a plurality of operations such as the operations above mentioned can be performed.

A feature of my invention comprises a series-of relatively adjustable burnishing tools, each except one serving as a gage when the next tool of the series is in use.

Another feature of my invention comprises a series of burnishing tools, each of which in the illustrated construction is mounted on an adjacent member of the series, and serves as a tread rest when an adjacent member of the series is being used.

These and other features of the invention comprising various combinations and arrangements of parts will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which,-

Figure 1 is a side elevation partially 111 section;

Fig. 2 is an end elevation, and

Specification of Letters Patent.

It' is Patented May as, 1918.

. Fig. 3 is an enlarged detail of the adjustlng means.

A shaft 10 is mounted in any suitable way for rotation. .It has .mounted' at its extremity a cylindrical head 11. Slidably mounted upon the outside of the head 11 is a head 12 outside of which is similarly mounted a head 13. These three heads have and 16 respectively upon their outside edges. The surface 14 has an element 1i adapted to run in the rand crease of a shoe.

.The three heads are relatively adjustable in position, the manner of this adjustment being shown in Fig. 3. A smooth channel 17 is formed in the inside edge of the head 13 and its outside end is covered by a plate 18. The channel contains a screw 19 which can be adjusted through a small aperture in the plate 18. The screw, which turns freely in the channel 17, engages a thread 20 on the head 12 so that by turning the screw the heads 12 and 13 can be relatively adjusted parallel to their axis. A similar adjusting structure is used between the heads 11 and 12 and is shown in cross section in Fig. 1.

The outside periphery of the heel is burnished by the surface 14 as shown in Fig. 1 and at 23 in-Fig. 2, the element 14 running in the rand crease, as a guide. The beading element 15 is used to form a bead around the external periphery of the heel as is shown at 22 in Fig. 2. The front fiat surface of the head 13 is used as a tread rest or gage in forming this bead. The adjustment described will make it possible to form this bead of any desired width. The small head 11 having the bead element 16 is used as shown at 21 in Fig. 2 to bead the breast of the heel, the header 16 being of sharp curvature in order to be able to work in the indentation 24 in the breast of the heel. The front fiat surface of the head 12 serves as a tread rest or gage in forming this head. The adjustment between the heads 11 and 12 will make it possible to make this bead of any desired width. It will thus be seen that I have provided a burnishing tool which shall be compact, convenient and cheap. It will be clear that the operator can perform all three operations upon the heel without changing his position -the burnishing or beading elements 14, 15

upon the floor and without changing the'position of the shoe in. his hand.

Having described my invention What I claim as new and desire to secure by United States-Letters -Patent is: i

1: ll burnishing instruinentality comprising a series of relatively adjustable burnishing tools each, except the last of the series, serving as v a gage WhentheneXt of the series is being used.

2. A burnishing instrumentality compris' ing a series of nested relatively adjustable burnishingjtools, eachllof thev larger. tools serving as a tread rest when the next .ad: jace'ntftool is being jused.

3. Aburnishing instrumentality compris-v ingra- "diamete-r ifroin one ,endof the series to "the otherand ealchof the largerjtools serving as a tread restv when the next smaller. tool is:
